myelin sheath
Generally, these would be the neurons and the supportive cells. Supportive cells, however, comprise several different kinds of cells. These include oligodendrocytes, glial cells, schwann cells, astrocytes, etc.
Almost fifty percent of the volume of neural tissue in the central nervous system is made up of glial cells. Glial cells provide support and insulation to neurons, help maintain homeostasis, and play a role in immune response in the brain and spinal cord.
The brain is made up of neurons, which are specialized cells that transmit information through electrical and chemical signals. The spinal cord is primarily composed of nerve tissue surrounded by protective membranes. Both the brain and spinal cord are also supported by glial cells, which provide structural support and help with functions such as insulation and waste removal.
The wrapping primarily made of lipids produced by some glial cells is called myelin. Myelin is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. This lipid-rich sheath insulates axons, facilitating faster electrical signal transmission along nerve fibers and contributing to the efficiency of neural communication.

Generally, these would be the neurons and the supportive cells. Supportive cells, however, comprise several different kinds of cells. These include oligodendrocytes, glial cells, schwann cells, astrocytes, etc.
The primary cell in the brain is the neuron. There are also many supporting cells, such as astrocytes, glial cells and the like.
Gray matter is primarily composed of cell bodies, dendrites, and glial cells. Cell bodies are the main component, containing the nucleus and organelles of neurons. Dendrites receive signals from other neurons, while glial cells provide support and nutrients to neurons.
The majority of the brain and spinal cord is made up of nervous tissue, specifically neurons and glial cells. Neurons transmit electrical signals, while glial cells provide support, protection, and nutrition for the neurons.

The spinal cord is primarily composed of nerve tissue surrounded by protective membranes. Both the brain and spinal cord are also supported by glial cells, which provide structural support and help with functions such as insulation and waste removal.
Roughly 50 percent of the volume of neural tissue in the CNS is comprised of glial cells. These cells provide support and protection for neurons, aiding in functions like insulation, nutrient supply, and immune defense. Glial cells also contribute to the maintenance of the blood-brain barrier.
cell wall
Epithelial tissue lines internal organs and acts as a protective covering for the skin. It is made up of tightly packed cells that form barriers to protect underlying tissues and organs from damage. Epithelial tissue also helps with absorption, secretion, and sensation.
A sea shell may contain a dead animal but the shell itself is a protective covering that an animal made to protect itself.
Neurons make up only about 10% of the cells in the nervous system but they play a crucial role in transmitting and processing information. Glial cells, which provide support and protection to neurons, make up the majority of cells in the nervous system.
